After their semifinal victory — on the Fourth of July, no less — these 35-year-old identical twins from California are one win away from becoming the first team in the history of Open-era tennis to hold all four major titles at the same time.

“The Bryan Slam,” they’ll call it, but don’t look for that news to knock baseball or Andy Murray out of the headlines in either the United States or Britain.

The Bryan brothers play doubles, and despite their history making success, they live in a world where their games aren’t fully appreciated.

If their list of accomplishments belonged to a singles player, they’d be considered among the best of all time.

Their 14 Grand Slam tournament titles would tie them for second with Pete Sampras.

Their 310 weeks at No. 1 would be eight more than Roger Federer’s record.

Their 90 tournament titles would rank third behind Jimmy Connors and Ivan Lendl.

They’ve raked in more than $20 million in prize money over their 15 years as pros and have gone 21-3 in Davis Cup matches.

Place them outside a tennis tournament, however, and they can walk down the street in peace.

“It’s the names and the stars,” said Jack Nicklaus, the 18-time major golf champion, who watched the Bryans play this week. “The singles players are really good, no question about that. If the doubles players were good enough, they’d be playing singles. To a large degree, I think that’s the way most people look at it.”

At the pro level, doubles can be an entertaining show, as was the brothers’ 6-7 (4), 6-4, 6-3, 5-7, 6-3 victory Thursday over the newly formed team of India’s Rohan Bopanna and France’s Edouard Roger-Vasselin.

“I think doubles have always taken a back seat since Open tennis and prize money settled it all,” said Pam Shriver, whose partnership with Martina Navratilova produced 20 Grand Slam titles. .
